EN Movement by Perfection The Royal League in ventilation, control and drive technology Modular System solution for AHU systems
Smaller is clever More flexibility with more fans, more air handling capacity, more efficiency The modular principle is a new approach to intelligent central air conditioning. In this modern technology, several (usually at least four) small fan units are connected in parallel in one housing instead of using one large fan. This arrangement has considerable advantages. On the one hand, the modular principle increases flexibility. Depending on the installation requirements, the number and size of fans can be selected optimally. On the other hand, it improves the air flow distribution: The result is a better heat transmission and filter utilisation in the central air conditioning unit. Operational reliability: No total failure in case of malfunction Using several small fans in place of one large fan improves depending on the installation requirements: In the event of a malfunctioning fan there is no total system failure and not even a drop in performance because, with the appropriate design, the speed of the other fans can be increased to compensate the non-operational fan.

High performance T* centrifugal impeller, the flow technical marvel with three-dimensional blade geometry, available in different configurations, suitable for a modular layout. *Also with steel wheel in the appropriate models An unbeatable team Modular system solution for maximum air handling capacity Handier, lighter, maintenance-free Services such as installation, maintenance and replacement also benefit: The individual modules weigh less and are easier to handle. Small fans also take up less mounting space. With ECblue motors there is no risk of drive belt failure thanks to a maintenance-free drive. Higher efficiency with lower noise level Smaller fans using ECblue motor technology benefit from a higher efficiency and ensure a reduction in the sound power level in the low frequency range. This means that less noise insulation is required which in turn has a positive effect on the length of the devices and the costs. Advantages: That added plus More operational reliability More performance More costs saved More installation flexibility More energy saved More maintenance friendliness the only less: Weight and space requirement! Alternatively in AC or ECblue technology In addition, not only AC but also ECblue motors with their very high efficiencies can be used.

GR modules with Technology : expandable to existing cross-section of the AHU As powerful as the big ones For air handling capacities way beyond 10,000 m 3 /h The modular system solution from ZIEHL-ABEGG, is highly flexible and due to the intelligent parallel circuiting of several fans, it can now also easily achieve air handling connection of 40,000 m 3 /h at pressures of 1000 Pa. This works not only with AC motors but also with ECblue motors. 4 4
The perfect combination, even greater power Everything is just perfect innovative fan system, intelligent control technology, high performance centrifugal fans and state of the art motor technology in AC and EC versions all from a single source. with integrated sine filter AC technology with Fcontrol frequency inverter ECblue motors with UNIcon control The Fcontrol frequency inverter is the perfect power controller for AC technology. With its integrated sine filter, Fcontrol guarantees a quieter and gentler motor operation regardless of power cable length: Optimised frequency inverter for parallel operation of multiple motors even with long motor power cables Sinusoidal output voltage (by integrated sine filter), comparable with the mains voltage. Therefore no stress for connected motors Ideal for the use of standard motors No need for shielded cables Emergency operation of the motors directly on the mains possible No electromagnetic motor noises High energy saving Quiet motor operation without the typical VSD motor whistle ECblue the trendsetting EC motor from ZIEHL-ABEGG is now also available with the innovative UNIcon control. This means: Maximum efficiency Simple installation and commissioning by a bus cable Automatic addressing of the fans ECblue sets the standard in terms of operation, efficiency and reliability: Ingeniously simple to operate Maximum efficiency Minimum electricity costs The innovative UNIcon control: External control signal, e.g. 0-10 V Differential pressure control Optional volume flow control and display 1 Modbus 2 3 6 5 4 5
Maximum efficiency minimum consumption Save energy with the power of multiples The alternative: Eight small ones instead of one big one Many can do what one cannot do alone. That is the great idea behind, the modular system solution which can replace one big fan with many small fans. Because, for the first time, the very high efficiencies of EC motors can be used for transporting large volumes of air with this system concept. Benefit from the enormous energy savings and maximum efficiency of the Ziehl-Abegg ECblue technology or choose Ziehl- Abegg AC motor technology with indestructible power and efficient perfomance with the matching control technology. GR modules with Technology and ECblue motors The agony of choice No matter which system or which solution you choose, you can t go wrong with ZIEHL-ABEGG Energy example calculation Options: An air handling unit has an operating point of 80,000 m 3 /h at a static pressure of 700 Pa. Device cross-section WxH = 3050 x 2800 mm. This corresponds to a speed in the device of 2.4 m/s (class V6). 1. Single ER11C fan with 37 kw AC motor + frequency inverter 2.
